16 Clinical Trials for Various Conditions
The purpose of this study is to closely observe people with desmoid-type fibromatosis over 1 months.
This study will assess the efficacy, safety, and tolerability of EN3835 compared to placebo in the treatment of PFI (also known as Ledderhose disease).
Assess the long-term safety and efficacy of EN3835 in participants who have participated in a parent placebo-controlled study of EN3835 (EN3835-222, NCT05152173) and assess the efficacy and safety of EN3835 in the treatment and retreatment of plantar fibromatosis.
This randomized, double-blind, placebo-controlled study will evaluate the efficacy and safety of up to 2 treatments of EN3835 vs placebo in participants with plantar fibromatosis.
This study evaluates nirogacestat (PF-03084014) in the treatment of desmoid tumor/aggressive fibromatosis (DT/AF). In the double-blind phase, half of the participants will receive nirogacestat while the other half will receive placebo. Once participants are eligible to roll into the open-label phase, they will receive nirogacestat.
This randomized phase III trial compares the effects, good and/or bad, of sorafenib tosylate in treating patients with desmoid tumors or aggressive fibromatosis. Sorafenib tosylate may stop the growth of tumor cells by blocking some of the proteins needed for cell growth. \[Funding Source - FDA OOPD\]
Background: * Desmoid tumors (also known as aggressive fibromatosis), are rare, locally invasive, slow-growing soft-tissue tumors. The disease can be either asymptomatic or be associated with severe loss of organ function and significant morbidity. * Treatment with the selective small-molecule Gamma-secretase inhibitor PF-03084014 caused significant tumor shrinkage in patients with unresectable desmoid tumors in an early phase clinical trial. * The Notch pathway is a key regulator of cell differentiation, proliferation and apoptosis; aberrant signaling via the Notch pathway is associated with carcinogenesis. Objectives: * Primary: Determine the response rate (Complete Response (CR)+Partial Response (PR)) of PF-03084014 in patients with desmoid tumors/aggressive fibromatosis * Secondary: Assess symptom measures at baseline and on study; perform genotyping for germline and somatic mutations in adenomatous polyposis coli gene (APC) and catenin-beta 1 (CTNNB1) genes; correlate clinical response to therapy with genotyping data; and assess modulation of the Notch pathway by evaluating notch response genes in tumor biopsies at baseline and after drug administration Eligibility: * Age greater than or equal to18; histologically confirmed desmoid tumor not amenable to curative resection or definitive radiation therapy that has progressed after receiving at least one line of standard treatment; adequate organ function * Willingness to provide blood samples and 10 unstained slides or a tumor block for genetic research studies Study Design: * This is an open-label Phase II trial of PF-03084014; study drug will be administered orally at 150 mg twice a day in 21-day cycles * Optional tumor biopsies for research purposes will be performed at baseline prior to study treatment and at the beginning of cycle 7 (+/- one cycle) * Restaging scans (magnetic resonance imaging (MRI) with diffusion weighting) will be performed at baseline, at the end of cycles 1 and 6, and then every 6 cycles * Health-related quality of life (HRQOL)/symptom questionnaires will be administered at baseline and at each Clinical Center visit
Desmoid-type fibromatosis (or desmoid tumor) represents an intermediate grade neoplasm with a striking predilection for locally invasive growth and recurrence following resection. It occurs in children as well as young adults. As a typically localized disease, the historical standard of care for treatment has been surgical resection, with or without ionizing radiation. In some cases where surgical resection or radiation is not feasible, chemotherapy has been used. Two clinical trials conducted in the Pediatric Oncology Group (POG) and the Children's Oncology Group (COG) evaluated the role for either low intensity or non-cytotoxic chemotherapy for children with desmoid tumor that is not amenable to standard therapy. These were largely empirical treatment strategies or based on somewhat anecdotal observations. By better understanding desmoid tumor biology, even more effective therapy targeting a particular protein that is central to the disease can be developed. Desmoid tumor is well-known to be associated with deregulation of the Adenomatous Polyposis Cell/beta-catenin (APC/β-catenin pathway). This is true of familial cases associated with Gardner's Syndrome and also in sporadic desmoid tumor, nearly all of which display histological or molecular evidence of Adenomatous Polyposis Cell/beta-catenin (APC β-catenin) pathway activation (Alman et al., 1997; Lips et al., 2009). Several new pieces of evidence support the concept that deregulation of the mammalian target of rapamycin (mTOR) cell proliferation/survival pathway may play an important role in tumor biology when the APC/β-catenin pathway is disrupted. Sirolimus, a drug that inhibits mammalian target of rapamycin (mTOR), is currently being evaluated as an anti-cancer agent in a variety of tumor types, but it has not been previously studied in desmoid tumor. The investigators are conducting this pilot study to begin to explore whether mTOR inhibition may be beneficial for children and young adults with desmoid tumor.
There is research supporting treatment of superficial fibromatoses (palmar fibromatosis and keloids) with triamcinolone acetonide injections. These lesions are histologically similar to deep fibromatoses (desmoid tumors). Currently there is little literature evaluating the response of desmoid tumors to injections of triamcinolone acetonide. The investigators aim to perform a pilot study evaluating the response of desmoid tumors to intralesional triamcinolone. If positive results are observed (based on RECIST criteria), then a phase II study will be initiated.
This phase II trial studies the side effects and how well nirogacestat works in treating patients less than 18 years of age with desmoid tumors that has grown after at least one form of treatment by mouth or in the vein that cannot be removed by surgery. Nirogacestat may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
This pilot clinical trial studies fluorine (F)-18 16 alpha-fluoroestradiol (18F-FES) positron emission tomography (PET)/computed tomography (CT) in imaging patients with desmoid tumors. 18F-FES binds to estrogen receptors, which are present on desmoid tumors, and gives off radiation that may be detected by PET and CT scans. The PET/CT scan forms an image that may show where tumor cells with estrogen receptors can be found in the body.
This phase I/II trial evaluates the highest safe dose, side effects, and possible benefits of tegavivint in treating patients with solid tumors that has come back (recurrent) or does not respond to treatment (refractory). Tegavivint interferes with the binding of beta-catenin to TBL1, which may help stop the growth of tumor cells by blocking the signals passed from one molecule to another inside a cell that tell a cell to grow.
This study gathers health information for the Project: Every Child for younger patients with cancer. Gathering health information over time from younger patients with cancer may help doctors find better methods of treatment and on-going care.
The purpose of the study is to compare the clinical outcomes of two commonly used, FDA-approved biologic meshes in hernia repair and abdominal wall reconstruction (Strattice and XenMatrix). The two meshes are derived from pig skin from which cells have been removed and which have been sterilized. The two meshes are made by two different companies using different processes.
The purpose of this study is to collect and store tumor tissue, blood, and bone marrow samples from patients with soft tissue sarcoma that will be tested in the laboratory. Collecting and storing samples of tumor tissue, blood, and bone marrow from patients to test in the laboratory may help the study of cancer.
This study will examine common features of gingival overgrowth (excessive growth of the gums around the teeth) that develops in patients with the hereditary form of the condition and in those who develop the condition as a side effect of medications. A better understanding of gingival overgrowth may help scientists develop medications with fewer oral side effects. Patients of any age with hereditary gingival fibromatosis and their blood relatives, and patients of any age with gingival overgrowth who are taking medications associated with development of the disorder, including phenytoin (diphenylhydantoin or Dilantin), cyclosporine, and calcium-channel blockers, may be eligible for this study. Participants undergo a medical and dental history, including a history of medication use; detailed examination of the teeth, periodontium, head, and neck; photographs of teeth with gingival overgrowth; dental x-rays; and blood tests. DNA is extracted from a blood sample to look for genes related to gingival overgrowth. Patients with gingival overgrowth are offered two options, as follows: * Tissue biopsy: A tissue sample is taken from each affected site, with a maximum of three biopsies. For the procedure, lidocaine is first injected into the gum to numb the tissue. Then, a cookie-cutter instrument is pushed into the numbed skin, and a small piece of tissue is removed. * Gingivectomy: Surgical removal of the overgrown gingival.
